IMPROVEMENT IN FIRE-PLACES.

fspoiilii-:liion Vorming part ol' Letters Patent No. 206,323, (lated .lilly '23, IRTS; application led January 11i, 1878.

To all lwhom 'it muy concern:

Re it known that I, (luenen II. Huss, o.' (Jhicago, in the county o'l' (look and State ot' Illinois, have invented certain In'iprovcmei'its in Fire-Places, of which the following is a specifica-tion:

The nature of this invention will be fully understood from the snbjoined description and the accompanying drawings, forming a part of this specification, in which drawings- Fi gure l is a central vertical section, from front to rear, of my improved tire-place; and Fig. 2 is a view oi' the same in, cross-section upon the line a' nu, indicated in Fig. 1.

Like letters of reference made use of in said drawings indicate like parts in all the figures.

In the drawings, A represents the grate, and A' the back, of the tire-place proper, such parts being of the ordinary construction. At the top the fire-place opens into a horizontal ilue, Il, leading directly into the chimney-liuc C. At the rear of the .ilue I3, and just before it debouches into the chimney, is placed a damper, I), operated from the front by the rod b'. Then this damper is open, the products of combustion pass unimpedcd into the chimney; but when it is closed they are forced down the descending flue D, which connects with B at a point in front of the damper. From l) the smoke passes into the chamber E at the bottom, and from thence into an ascending flue, F, whence it finds egress through the chimney. These flues B, D, and F are made of' metal, in order that the heat passing through them may be utilized iu heating the air in the chamber Gr, which surrounds them upon all sides. The back A of the fireplace is also made of metal, for a similar reason.

If it is desired to obtain greater radiatingsurface than single iiues will afford, then they may be duplicated, with a space i between them, and in such case the duplicate lines B may be connected by crossrducts B', which are preferably set at an angle, as shown, to direct the ascending air in chamber G toward the outlet H, hereinafter mentioned. In any case the horizontal iiue should be perforated for the direct passage of the hot air to the outlet H.

Air is drawn from near the floor of the room through a duct, I, placed at the bottom of the side ol' the lire-place, and is by it comliwted around to the rear of the ilue F and discharged into the air-space (l at the point I. \Vhen in (l it comes in contact with the outside surfaces of the i'lues II, l), and F, and also with the back A! oi.' the lire-place., and, as it becomes heated thereby, rises, and finds an outlet into the room through the opening II inst over the gra-te.

It is intended that the openings I and Il shall be open at all times; but they may be constructed so that the circulation ot' air through them may be controlled when the heat becomes too great. It' desired, the airduct I may be iliade to communicate, at any point in its course, with the external air, and to draw its supplies, either wholly or partially, therefrom.

Of course the heating-surface in the airchamber (l will be very much reduced when the direct draft through the iiue I3 into the chimney is used, but there will still be enough to produce movement ol' the air through the chamber, and it is thus seen. that no heat is allowed to escape through the chimney without doing some service toward heating the rooln.

At K, under the grate, is a door opening into the chamber ll, to ait'ord an opportunity for cleaning that chamber and the iiues connecting therewith. This door I provide with a register, as shown, which will be found useful in that a suction is thereby created which draws into said chamber, and thence out through .flue F, a large portion ofthe dust and ashes, which would otherwise find its way into the room.

rIhe advantages attending my improvements, which I have found by experiment, are that they secure an admirable circulation of the air and even distribution of the heat throughout the room, and enable me to obtain much more heat from the same amount of fuel than can be obtained from the ordinary form of fire-place.

Having thus described my invention, what I claim as new, and desire to secure by Ilettcrs latent, is-

1. The combination, with an open tire-place, ofthe air space or chamber G, the llues 13,1), and F, surrounded by and passing through said chamber, the flue B being,` provided with 3. The combination, with the air-chamber the damper b, as specified, the chamber E, the Gr, traversed by smoke-dues, substantially :is air-duct I, :uid the outlet IT, the whole zirdescribed, of the inlet .I and outlet H, placed ranged and constructed subsmntinllyas specior located :md construct-ed as shown, subied. smntially :ls mid for the purposes specified.

2. The combination, with the outlet II, of l the air-passages formed between the duplicate G EO. 1I. NESS.
